pybanyan 0.16.0

API library and command-line interface for Banyan Security

API library and command-line interface for Banyan Security

Prerequisites

Python 3.7 or 3.8 must be installed.

Installation

Installing the easy way

$ pip install pybanyan

Installing the hard way

$ git clone https://github.com/banyansecurity/pybanyan.git
$ cd pybanyan
$ pip install -r requirements.txt
$ python setup.py install

Usage

This package contains both an API client and a CLI tool. To use either one, you need to generate an API token from the Banyan Command Center.

API library

Here's a sample script that uses the library to print the names of every service registered in Banyan:

from banyan.api import BanyanApiClient

c = BanyanApiClient()
for service in c.services.list():
    print(service.name)

Output:

$ python examples/list_services.py
jira
jupyter
kube
mysql
rds-mysql
rds-pgsql

The BanyanApiClient class accepts optional arguments to specify the API server and refresh token. If not provided, it gets them from environment variables named BANYAN_API_URL and BANYAN_REFRESH_TOKEN.

Full API documentation will be available soon.

Banyan CLI tool

Before you use the CLI, create a file called ~/.banyan.conf in your home directory and paste in your API token:

[banyan]
api_url = https://net.banyanops.com
refresh_token = MY_API_TOKEN

The CLI is invoked with the banyan tool. It contains a number of commands and sub-commands to help you work with policies, roles, services, users, and other objects in Banyan.

Run the banyan tool by itself to see the available commands.

$ banyan
usage: banyan [options] <command> <subcommand> [<subcommand> ...] [parameters]

$ banyan service
usage: banyan service [-h]
                      {attach-policy,create,delete,detach-policy,disable,enable,get,list,test,update}
                      ...

  -h, --help            show this help message and exit

    detach-policy       detach the active policy from a service
    disable             disable a service
    enable              enable a service

                                    service_name_or_id policy_name_or_id
